Ringer is a dedicated and upright young police officer in the harbor. He and his two subordinates and friends, the talented but somewhat cynical Wan Xing and the agile but overly jealous Su Li, are jointly responsible for a drug trade case in the harbor. Tang Tang is a bright-eyed and academic girl in Tianjing. The two people who were strangers met and fell in love by chance. However, the road to falling in love was not smooth sailing. The death of Lin Ge's parents when he was a teenager, the betrayal of his previous girlfriend, and the fact that Tang Tang's ex-boyfriend was an acquaintance of his made him suspicious. In the end, Tang Tang almost gave his life for him, but later he suddenly realized that he lost Tang Tang because of Tang Tang's amnesia. The hopeless Lin Ge chose to work as an undercover agent in a dangerous foreign country. In the end, will Tang Tang, who has found his memories, wait for Lin Ge?
